1 / 8 page 5-1 FACT DATA Dual 4Input Multiplexer with 3State Outputs The MC74AC353/74ACT353 is a dual 4-input multiplexer with 3-state outputs. It can select two bits of data from four sources using common Select inputs. The outputs may be individually switched to a high impedance state with a HIGH on the respective Output Enable (OE) inputs, allowing the outputs to interface directly with bus-oriented systems. • Inverted Version of the MC74AC253/74ACT253 • Multifunction Capability • Separate Enables for Each Multiplexer • Outputs Source/Sink 24 mA • ′ACT353 Has TTL Compatible Inputs 15 16 14 13 12 11 10 2 1 3 4 5 6 7 VCC 9 8 OEb S0 I3b I2b I1b I0b Zb OEa S1 I3a I2a I1a I0a Za GND PIN NAMES I0a–I3a Side A Data Inputs I0b–I3b Side B Data Inputs S0, S1 Common Select Inputs OEa Side A Enable Input OEb Side B Enable Input Za, Zb Multiplexer Outputs TRUTH TABLE Select Inputs Data Inputs Output Enable Outputs S0 S1 I0 I1 I2 I3 OE Z X X X X X X H Z L L L X X X L H L L H X X X L L H L X L X X L H H L X H X X L L L H X X L X L H L H X X H X L L H H X X X L L H H H X X X H L L Address inputs S0 and S1 are common to both sections.
